Description

Gepanzertes, schwimmfähiges Fahrzeug Armored, buoyant vehicle
Die Erfindung betrifft ein gepanzertes, schwimmfähiges Fahrzeug, mit Auftriebskörpern zur Verbesserung des Auftriebs sowie eine Verfahren zur Herstellung eines Auftriebskörpers.The invention relates to an armored, buoyant vehicle, with buoyancy bodies to improve the buoyancy and a method for producing a buoyant body.
Fahrzeuge dieser Art sind beispielsweise bekannt durch die US2002022415, die US2003172863 oder die US2OO5145157. Diese haben zur Verbesserung des Auftriebs ziehharmonikaartig ausfaltbare und somit kammerbildende Auftriebskörper, die beim Fahren an Land zusammengefaltet hinter einer Stahlklappe verborgen sind. Das Ausfalten erfolgt entweder unmittelbar durch Aufblasen oder mittels eines pneumatisch oder hydraulisch betätigten Gestänges. Solche Auftriebskörper verursachen jedoch im aktiven Zustand einen hohen Strömungswiderstand des Fahrzeuges und ihr Betätigungsmechanismus ist aufwändig und entsprechend störanfällig. Auch besteht die Gefahr, dass die hohlen Auftriebskörper infolge Geschosseinwirkung undicht werden und sich folglich mit Wasser füllen, so dass ihr Auftrieb verloren geht und sie nicht mehr schliessbar sind.Vehicles of this type are known for example from US2002022415, US2003172863 or US2005145157. These have to improve the lift accordion-like foldable and thus chamber-forming buoyancy bodies, which are hidden when driving ashore behind a steel flap. The unfolding takes place either directly by inflation or by means of a pneumatically or hydraulically actuated linkage. However, such buoyant bodies cause a high flow resistance of the vehicle in the active state and their actuating mechanism is complex and prone to failure. There is also the danger that the hollow buoyancy bodies will leak as a result of projectile action and consequently fill up with water, so that their buoyancy is lost and they can no longer be closed.
Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile zu vermeiden und ein Fahrzeug der eingangs genannten Art zu finden, dessen Auftriebskörper sich auf einfache und zuverlässige Weise montieren und auch demontieren lassen und die sich optimal der Fahrzeugstruktur anpassen lassen, so dass der Strömungswiderstand im Verhältnis zur erzielten Auftriebswirkung nur gering zunimmt und das äussere Erscheinungsbild des Fahrzeuges auch hinsichtlich seiner Tarnung bzw. hinsichtlich seiner Wärme-, Radar-, akustischen und optischen Signatur vorteilhaft verändert wird. Insbesondere soll auch die dauerhafte Wirkung seiner Vorrichtungen zur Verbesserung des Auftriebs z.B. auch nach Geschosseinwirkung sicher gestellt sein. Die Lösung dieser Aufgabe erfolgt erfind ungsgemäss dadurch, dass die Auftriebskörper aus einem geschlossenporiger Schaumkunststoff geformt sind und als Formkörper an die Fahrzeugkontur angepasst sind.The invention has for its object to avoid the disadvantages mentioned and to find a vehicle of the type mentioned, the buoyancy of which can be assembled and disassembled in a simple and reliable manner and can be optimally adapted to the vehicle structure, so that the flow resistance in proportion only slightly increases the buoyancy effect achieved and the external appearance of the vehicle is also advantageously changed in terms of its camouflage or in terms of its heat, radar, acoustic and optical signature. In particular, the long-term effect of his devices to improve the buoyancy should also be ensured, for example, after projectile action. The solution of this object is achieved according to the invention in that the buoyancy bodies are formed from a closed-cell foam plastic and are adapted as a molded body to the vehicle contour.

Ein Fahrzeug 1 der in Fig. 1 bis Fig.2 dargestellten Art ist beispielsweise durch die EP 1291610 bekannt. Da der Fahrzeugkörper 2 gegen eindringendes Gas oder Wasser zwar grundsätzlich abgedichtet ist, kann das Fahrzeug auch amphibisch eingesetzt werden. Bei Anbringung einer zusätzlichen Panzerung und/oder von schweren Waffensystemen wird jedoch das für amphibischen Einsatz zulässige Fahrzeuggesamtgewicht überschritten, so dass der Fahrzeugkörper 2 zu weit im Wasser eintaucht und ein sicherer amphibischer Einsatz nicht mehr gewährleistet ist.A vehicle 1 of the type illustrated in FIGS. 1 to 2 is known, for example, from EP 1291610. Although the vehicle body 2 is fundamentally sealed against penetrating gas or water, the vehicle can also be used amphibiously. When attaching an additional armor and / or heavy weapons systems, however, the permissible for amphibious use total vehicle weight is exceeded, so that the vehicle body 2 immersed too far in the water and safe amphibious use is no longer guaranteed.
Für eine wesentliche Verbesserung des Auftriebs sind erfindungsgemäss am Fahrzeug 1, seiner Kontur 3 angepasst, Auftriebskörper 4,5 vorgesehen.For a substantial improvement of the lift, according to the invention, buoyant bodies 4, 5 are adapted to the vehicle 1, its contour 3.
Entsprechend der aus Fig. 4, 8 bis 11, 14 und 15 ersichtlichen Querschnittform der Auftriebskörper 4, 5 folgt ihre obere Begrenzungsfläche 6,7 durch ihre Neigung dem Verlauf der seitlichen Dachflächenbereiche 8 und 9 des Fahrzeuges 1. Ausserdem folgt ein oberer Bereich 10, 11 ihrer Innenflächen dem Verlauf der steil geneigten Seitenflächen 12, 13 des Fahrzeuges 1, so dass sie sich grossflächig an diesem abstützen. Eventuell von diesen Seitenflächen 12,13 abstehende Ausrüstungsteile des Fahrzeuges 1 können auf nicht dargestellte Weise in entsprechend geformten, örtlichen Ausnehmungen der Auftriebskörper 4,5 aufgenommen werden. Wie in Fig.4, Fig.5 und Fig.7 oder auch in Fig.8 gezeigt, setzt sich im Bereich der nichtlenkbaren Räder 14, 15, 16 ein unterer Innenflächenbereich 17, 18 der Auftriebskörper 5, 6 nach unten so weit fort, dass ein oberer Bereich der nichtlenkbaren Räder überdeckt wird. Dieser sich somit weit nach unten erstreckende Bereich der sich durch die Auftriebskörper 4, 5 ergebenden Fahrzeugummantelung führt zu einer teilweisen Schliessung der Radkästen, mit entsprechenden Vorteilen hinsichtlich der Fahrzeugsignatur, insbesondere auch hinsichtlich der Verringerung von Fahrgeräuschen und einer Staubaufwirbelung beim Landeinsatz des Fahrzeuges 1.According to the cross-sectional shape of the buoyancy bodies 4, 5 apparent from FIGS. 4, 8 to 11, 14 and 15, their upper boundary surface 6, 7 follows the course of the lateral roof surface areas 8 and 9 of the vehicle 1 by virtue of their inclination. 11 of their inner surfaces the course of the steeply inclined side surfaces 12, 13 of the vehicle 1, so that they are supported on a large area at this. Possibly out of these side surfaces 12,13 protruding pieces of equipment of the vehicle 1 can be recorded in a manner not shown in correspondingly shaped, local recesses of the buoyancy 4,5. As shown in FIGS. 4, 5 and 7 or also in FIG. 8, in the region of the non-deflectable wheels 14, 15, 16, a lower inner surface area 17, 18 of the buoyancy bodies 5, 6 continues so far downwards, that an upper portion of the non-steering wheels is covered. This region of the vehicle casing resulting from the buoyancy bodies 4, 5, thus extending far downwards, leads to a partial closure of the wheel arches, with corresponding advantages with regard to the vehicle signature, in particular also with regard to the reduction of driving noise and a raising of dust during land use of the vehicle 1.
Die Aussenfläche 19, 20 der entsprechend der Darstellung in Fig.5 und 6 in Reihe hintereinander am Fahrzeug 1 befestigten Auftriebskörper 4, 5 kann sowohl hinsichtlich optimaler Fahrzeugsignatur als auch hinsichtlich strömungsgünstiger Formgebung frei gestaltet werden.The outer surface 19, 20 of the according as shown in Figure 5 and 6 in series one behind the other on the vehicle 1 attached buoyancy body 4, 5 can be designed freely both in terms of optimum vehicle signature and in terms of aerodynamic design.
Ein Beispiel einer den Strömungswiderstand des Fahrzeuges 1 verringernden Formgebung ist durch die Darstellung in Fig.6 gezeigt, indem dort die Aussenfläche 19 bis 22 der in Fahrtrichtung vorderen und hinteren Auftriebs körper 4, 5 in Fahrzeuglängsrichtung nach Art eines Schiffsbugs und Schiffshecks nach innen abgeschrägt ist.An example of a flow resistance of the vehicle 1-reducing shaping is shown by the representation in Figure 6, there is the outer surface 19 to 22 of the front and rear buoyancy in the direction of travel body 4, 5 is tapered in the vehicle longitudinal direction like a ship's bow and stern towards the inside ,
Zur weiteren Verbesserung des Auftriebs, ohne Vergrösserung der Breite des Fahrzeuges 1, können sich die im Bereich der nicht angetriebenen Räder 14, 15 vorgesehenen Auftriebskörper 23 derart nach innen erstrecken, dass sie einen durch die Räder 14, 15 nicht beanspruchten Innenbereich der Radkästen 24 ausfüllen. Fig.10 zeigt ein Beispiel eines sich vom unteren Innenflächenbereich 17, 18 eines Auftriebskörpers 23 in den Radkasten 24 hinein erstreckenden Querkörpers 25, mit Abschrägungen 26, 27, die parallel zu einer Tangente an den Rädern 14,15 des Fahrzeuges 1 verlaufen, aber auch gekrümmt, dem Radumfang angepasst, geformt sein können. Eine weitere besondere, die Wasserströmung im Bereich der Propeller 28, 29 verbessernde Formgebung kann entsprechend der Darstellung in Fig. 9 und Fig.10 für die dort befestigten Auftriebskörper 30,31 vorgesehen sein. Entsprechend der Ansicht nach Fig.9 ist in den unteren Teil 32 des Auftriebskörpers 31 ein im Querschnitt halbrunder, der äus- seren Umlauffläche des Propellers 29 angepasster, in Fahrzeuglängsrichtung verlaufender Strömungskanal 33 eingeformt. Der sich ergebende Strömungsverlauf ist durch die schematisch dargestellten Strömungslinien 33,24 angedeutet.To further improve the buoyancy, without increasing the width of the vehicle 1, the buoyancy bodies 23 provided in the region of the non-driven wheels 14, 15 can extend inwards in such a way that they fill an interior region of the wheel arches 24 which is not stressed by the wheels 14, 15 , 10 shows an example of a transverse body 25 extending from the lower inner surface area 17, 18 of a buoyant body 23 into the wheel house 24, with chamfers 26, 27 that run parallel to a tangent to the wheels 14, 15 of the vehicle 1, but also curved, adapted to the wheel circumference, can be shaped. A further special shaping which improves the water flow in the area of the propellers 28, 29 can be provided as shown in FIGS. 9 and 10 for the buoyancy bodies 30, 31 fastened there. Corresponding to the view according to FIG. 9, in the lower part 32 of the buoyant body 31, a flow channel 33 which is half-round in cross-section and adapted to the outer circumferential surface of the propeller 29, extending in the vehicle longitudinal direction, is formed. The resulting flow profile is indicated by the schematically illustrated flow lines 33,24.
Die dargestellten und beschriebenen Ausführungsformen von am Fahrzeug lösbar befestigten Auftriebskörpern 4, 5, 23, 30, 31 veranschaulichen die erfindungsgemäss mögliche, grosse Variabilität der Formgebung der Auftriebskörper 4, 5, zur optimalen Anpassung hinsichtlich verschiedener, durch die Fahrzeugstruktur vorgegebener Anforderungen. So ist es beispielsweise mit geringem Aufwand möglich, an der dem Fahrzeugkörper 2 zugekehrten Innenseite der Auftriebskörper 4, 5 nichtdargestellte Aussparungen einzuarbeiten, um an der Fahrzeugseitenwand vorgesehene, Erhebungen bildende Ausrüstungsteile um- schliessen zu können, so dass diese für einer dichte Anlage der Auftriebskörper 4, 5 an den Fahrzeugseitenflächen 12, 13 nicht hinderlich sind.The illustrated and described embodiments of liftable bodies 4, 5, 23, 30, 31 releasably secured to the vehicle illustrate the large variability of the shape of the buoyancy bodies 4, 5, which is possible according to the invention, for optimum adaptation to different requirements imposed by the vehicle structure. Thus, it is possible, for example, with little effort to incorporate recesses not shown at the inside of the buoyancy bodies 4, 5 facing the vehicle body 2 in order to be able to enclose the surveying equipment provided on the vehicle side wall so that the buoyancy bodies 4 are tightly arranged , 5 on the vehicle side surfaces 12, 13 are not a hindrance.
Diese grosse Variabilität der Formgebung wird auf einfache und damit kostengünstige Weise dadurch erreicht, dass die Auftriebskörper aus einem geschlossenporigen und damit leicht bearbeitbaren Schaumkunststoff geformt sind, wie durch die Darstellungen in Fig.11 und Fig.14 gezeigt ist. Entsprechend lässt sich der jeweilige Auftriebskörper auf einfache Weise, z.B. durch die formgebende Bearbeitung eines Rohmaterialkörpers mittels für die Schaumstoffbearbeitung üblichen Schneid - oder Fräswerkzeugen in der gewünschten Form herstellen. Die für den militärischen Fahrzeugbetrieb erforderliche mechanische Oberflächenfestigkeit ergibt sich durch eine nach der Formgebung des Auftriebskörpers erfolgende Beschichtung 35, z.B. mittels eines zähen Kunststofflaminats. Die für die Anordnung in höher beanspruchten Fahrzeugbereichen vorgesehenen Oberflächen¬ bereiche der Auftriebskörper, z.B. im Bereich der Radkästen 24, können jedoch auch stattdessen oder zusätzlich durch Aluminiumblech geschützt sein. Weiterhin können, durch die Ausbildung der Auftriebskörper aus einem geschlossenporigen Schaumkunststoff, in diesen auf einfache Weise Vertiefungen, Kanäle oder andere Formen eingearbeitet werden, die ihre lösbare Befestigung am Fahrzeugkörper 2 ermöglichen.This great variability of the shaping is achieved in a simple and therefore cost-effective manner by virtue of the fact that the buoyancy bodies are formed from a closed-cell foam plastic which is thus easy to process, as shown by the illustrations in FIG. 11 and FIG. Accordingly, the respective buoyant body can be produced in a simple manner, for example, by the shaping of a raw material body by means of cutting or milling tools customary for foam processing, in the desired shape. The mechanical surface strength required for military vehicle operation results from a coating 35 taking place after the shaping of the buoyant body, for example by means of a tough plastic laminate. The For the arrangement in higher-stressed vehicle areas provided surface ¬ areas of the buoyancy bodies, for example in the area of the wheel arches 24, but may instead or additionally be protected by aluminum sheet. Furthermore, by the formation of the buoyancy body of a closed-cell foam plastic, in these recesses, channels or other forms can be incorporated in a simple manner that allow their releasable attachment to the vehicle body 2.
Die weiteren Ausführungsbeispiele der Erfindung entsprechend den Darstellungen der Fig. 16 und 17 zeigen, dass die Auftriebskörper 4 auch in seilticher Ansicht des Fahrzeuges verschieden profiliert sein können, um unter Berücksichtigung von im Bereich der Räder erforderlichen Freiräumen, einen maximalen Auftrieb und Vorteile hinsichtlich der Fahrzeugsignatur zu erreichen.The further embodiments of the invention according to the representations of FIGS. 16 and 17 show that the buoyancy bodies 4 can also be profiled differently in a rope-like view of the vehicle in order to obtain maximum buoyancy and advantages with regard to the vehicle signature, taking into account the clearances required in the area of the wheels to reach.
Für die Befestigung von Auftriebskörpern 36 haben solche entsprechend dem Ausführungsbeispiel nach Fig. 14 oder Fig.15 zwei sich quer hindurch erstreckende Gurtkanäle, mit sich kanalförmig anschliessenden Führungskanälen 40, für die Aufnahme von jeweils einem Spanngurt 41 in üblicher Ausführung. Die schematische Darstellung der Fig.15 zeigt zu dem Spanngurt 41 zugehörige Spanngurtteile 42, d.h. ein Gurtende zur Einführung in das Schnallenende 44 des Gurtes 41 und eine Spannratsche 43, zur Aufnahme und zum Spannen des oberen, freien Gurtendes 45.For the attachment of buoyancy bodies 36 have those according to the embodiment of FIG. 14 or Fig. 15 two transversely extending belt channels, with channel-shaped subsequent guide channels 40, for receiving each a tension belt 41 in the usual version. The schematic representation of Figure 15 shows the tension belt 41 associated Spanngurtteile 42, i. a strap end for insertion into the buckle end 44 of the strap 41 and a tensioning ratchet 43 for receiving and tensioning the upper free strap end 45.
Eine weitere Ausführungsform eines lösbaren Befestigungssystems für die Befestigung eines Auftriebskörper 4 am Fahrzeug 1 ist in den Fig.11 bis 13 dargestellt. Dieses hat einen unteren, am Fahrzeug z.B. mittels Schrauben 46 befestigten Rastzapfen 47 für die Ein¬ klinkung in einer unteren, innenseitigen Rastöffnung 48 des Auftriebskörpers 4 und einen obere, z.B. mittels Schrauben 49 befestigten Rasthaken 50 für die Aufnahme eines Bü¬ gels 51 einer Spannklinke 52. Bei einem solchen Befestigungssystem müssen im Auf- triebskörper 4 Trägerplatten 53 oder Trägerprofile 54 für die Anbringung solcher Befestigungsmittel 48, 51, 52 eingearbeitet und z.B. durch Kleben befestigt sein.A further embodiment of a detachable fastening system for fastening a buoyancy body 4 on the vehicle 1 is shown in FIGS. 11 to 13. This has a lower, fixed to the vehicle eg by means of screws 46 latching pin 47 for the ¬ clinking in a lower, inside detent opening 48 of the buoyancy body 4 and an upper, for example by means of screws 49 attached latching hook 50 for receiving a Bü ¬ gel 51 a tensioning pawl 52. In the case of such a fastening system, Drive body 4 support plates 53 or support profiles 54 for the attachment of such fasteners 48, 51, 52 incorporated and attached, for example by gluing.
Die Grosse der einzelnen am Fahrzeug an den vorgegebenen Befestigungsstellen lösbar und damit auch austauschbar zu befestigenden Auftriebskörper 4, 5, 23, 30 ,31 wird so gewählt, dass sie für eine oder zwei Personen hinsichtlich ihres Gewichtes ausreichend handlich sind, um sie leicht zu tragen und ihre Befestigungsmittel betätigen zu können. Hierzu können die Auftriebskörper zusätzlich zur Fahrzeuglängsrichtung auch für eine Anordnung vertikal übereinander unterteilt und durch nichtdargestellte Befestigungsmittel lösbar miteinander verbunden sein, wie durch die Trennlinie 55 in Fig.9 und Fig. 10 angedeutet ist.The size of each of the vehicle at the predetermined attachment points detachable and thus also exchangeable to be attached buoyant body 4, 5, 23, 30, 31 is chosen so that they are sufficiently handy for one or two people in terms of their weight to carry them easily and be able to operate their fasteners. For this purpose, in addition to the vehicle longitudinal direction, the buoyancy bodies can also be subdivided vertically above one another for an arrangement and can be detachably connected to one another by fastening means, not shown, as indicated by the parting line 55 in FIG. 9 and FIG.
Aufgrund des somit offensichtlichen Baukastenprinzips kann die Anzahl und Verteilung derartiger Auftriebskörper 4, 5 entsprechend dem gewünschten oder erforderlichen Auftrieb unterschiedlich vorgenommen werden, um je nach Ausrüstung, z.B. mit einem Ge¬ schütz 55 entsprechend Fig.5 und deren Anordnung im oder am Fahrzeug 1 dessen opti¬ male Schwimmlage auszutarieren. Entsprechend der schematischen Darstellung in Fig.7 sind die Auftriebskörper 4, 23 hierzu beispielsweise auf den vorderen und mittleren Bereich des Fahrzeuges 1 beschränkt. Due to the thus obvious modular principle, the number and distribution of such buoyancy bodies 4, 5 can be made differently according to the desired or required buoyancy to depending on the equipment, eg with a ge ¬ contactor 55 according to Figure 5 and their arrangement in or on the vehicle 1 balance out opti ¬ male swimming position. According to the schematic illustration in FIG. 7, the buoyancy bodies 4, 23 are restricted for this purpose, for example, to the front and middle regions of the vehicle 1.
